What action did Giampaolo fail to perform despite promising Isabella?

• A. Call her
• B. Visit her
• C. Text her
• D. Email her

Answer: (A)

The central idea here is following through on a promise about how to communicate. If Giampaolo promised Isabella he would reach out by phone but didn’t actually make the call, the action he failed to perform is calling her. The other options describe different ways of contacting someone, but the prompt specifies the missed action was a phone call, not a visit, text, or email.
